YIELECTRIC COATINGS ON VEHICLES CAN ALTER THEIR RADAR IMAGE SIGNIFICANTLY. THIS PROPOSAL IS DIRECTED TO DETERMINING NUMERICALLY THE REFLECTIVITY FOR AN OBJECT COVERED BY A DIELECTRIC LAYER. A CALCULATION WILL BE DONE USING BASIC PHYSICAL PRINCIPLES TO DEFINE THE THEORETICAL BOUNDARY VALUE PROBLEM FOR THE DIELECTRIC LAYER. THE SOLUTION TO THIS PROBLEM WILL BE OBTAINED NUMERICALLY USING MATRIX INVER ...

A small, personnel, battlefield, fiber optic sensor for detection of heartbeat and respiration rates will be developed. This biosensor offers high sensitivity, simplicity of design, and low costs. The contractor will show the feasibility of a personnel biosensor which has the potential to signal fatigue, dehydration, stress, illness, injury, or sleep disorders which are detectable through low fr ...

Wind noise in outdoor measuemetn micropnones can mask an acoustic signal. Windscreens provide some wind noise reduction; however, those typically used for outdoor applications provide noise reductions of approximately 10-15 dB. Planning Systems Incorporated (PSI) proposes to design and test a Multiple Aperture Sensor System (MASS) consisting of a microphone, a processor, and data acquisitio and ...

The current market for fast switching frequency sythesizers is growing rapidly. Most synthesizers available today will not meet the stringent requirements for switching quickly, providing spectrally pure RF outputs and minimizing physical size and cost. As part of a current SBIR program, S.T. Research has developed a wideband, fast switching synthesizer, based on the use of broadband phase-locke ...

Large field-of-regard (FOR) scanners are often desirable for poassive and active optical-infrared (IR) sensor systems for applications such as imaging, ladar, precision munitions, space-based surveillance, security surveillance, remote sensing, and free-space optical communications. The large FOR scanners for precision munitions need to be fast, small, light, rugged, low in power consumption, and ...

The production of semi-conductor wafers is a multibillion dollar industry. The 1996 worldwide semiconductor market is estimated at $162 billion with a growth potential to $309 billion by the year 2000. Thus, even a small improvement in control during the manufacturing process could have a large impact on the economic viability of many companies and products. A critical factor in all semiconduct ...

WHAT IS BEING PROPOSED IS THE DEVELOPMENT OF PERMANENT MAGNET BRUSHLESS DC MOTORS USING NEODYMIUM BORON IRON AS THEPERMANENT MAGNET MATERIAL. THIS MATERIAL, NEWLY INTRODUCED AT THE MMM CONFERENCE IN PITTSBURGH ON NOVEMBER 10, 1983, SEEMS TO HOLD THE POTENTIAL FOR SIZE WEIGHT REDUCTIONS FOR A GIVEN LEVEL OF OUTPUT OVER ANY OTHER PM MATERIAL CURRENTLYAVAILABLE INCLUDING RARE EARTH COBALT MAGNETS AND ...

THIS STUDY WILL EXAMINE THE FEASIBILITY AND PRACTICALITY OF UTILIZING CHARCOAL CLOTH IN A LIGHT-WEIGHT SOLAR POWERED DISTILLATION PURIFICATION DEVICE INCORPORATING CHARCOAL CLOTH AS THE ENERGY ABSORBENT WATER WICK. IN THIS PROPOSED DEVICE, IT IS EXPECTED THAT THE CHARCOAL CLOTH WILL ACT NOT ONLY AS THE DISTILLATION MEDIA, BUT WILL ALSO REMOVE OBJECTIONABLE ODORS, CO-DISTILLABLE ORGANIC COMPOUNDS A ...
